This invention relates to slide fasteners and, in particular to a new and improved method of making pulls for the sliders thereof.

It is an object of this invention to provide a new and improved method of inaking pulls for slide fasteners embodying a manually engageable bead chainfacilitating actuation of the slider,

in opening and closing a slide fastener, by exertion of tension longitudinally upon the slider through the pull tab thereof.

This and other objects of the invention will appear from the following description taken in conjunction with theaccompanying drawing which forms a part thereof, and will be pointed out in the appended claim.

In the drawing: Fig. 1 is a view, in perspective, of a slide fastener slider having a pull tab provided with a bead chain according to the principles of this invention, the bead chain forming a loop by reason'of attachment of both ends thereof to the I slider pull tab;

Fig. 2 is'a view similar to Fig. 1 of a modified pulltab construction wherein one end only of a bead chain is attached to the pull tab;

Fig. 3 is an enlarged transverse section taken substantially on the line 3-3 of Fig. 2;

Fig. 4 is a fragmentary enlarged longitudinal- .section through the bead chain, taken substantially on the line 4-4 of Fig. 2, and illustrating the construction of the bead chain;

Fig. 5 is a fragmentary view, partly in section and partly in elevation, illustrating the first step of my method of attaching a bead chain to the pull tab of a slide fastener slider; and

-Fig. 6 is a view similar to Fig. 5, but illusof-the method illustrated in Fig. 5. I

Referring to the drawing in detail, Figs. 1 and 2 show slider constructions of conventional form comprising slider bodieslll with lugs I I, by means (I): which pull tabs 12 are supported on the bodies The pull tab l2 of the slider shown in Fig. 1

i is provided with a pair'of apertures ll extending In the'construction shown in Fig; 2, only one .end bead member ll of the bead chain I6 is secured in thesingle aperture provided in the pull tab I2 and, consequently, only one notch I5 is provided for receiving the single .member is attaching this and bead member H to the adjacent bead member ll of the bead chain I6.

The construction of the bead chain is best illustrated in Fig. 4, wherein it will be seen that each bead member ll is provided with aligned oppositely disposed apertures i8, through each of which apertures one end of a link member 19 extends. The link members is ar'eprovided at each end with enlarged heads 20 for maintaining the connection of adjacent bead members ll by intermediate links is, as shown in Fig, 4.

The head chain illustrated in Fig. 1 is provided at its mid-portion with .an enlarged bead member Ila for facilitating manual engagement of the bead chain It, while a similar enlarged bead member Ila is provided at the free end of the bead chain I6 illustrated in Fig. 2.

A preferred method of securing an end bead member ll in each aperture ll of a pulltab I2 .is shown in Figs. 3, 5=and 6. According to this method, an aperture Ha (Fig. 5) is formed, in suitable location, in the pull tab II with a suitably located notch l5 leading therefrom. An end bead member ll of a bead chain I6 is then placed in the aperture a with its attached link I9 extending through the notch l5 and the asmitting axial movement of the opposed setting therethrough from side to side adjacent the free end thereof, and with a notch l5 leading from each aperture to the free end of the slider. Each end bead member ll of a bead chain, generally designated i6, is secured, either rigidly or pivotally,'in each aperture ll in a manner hereinafter most clearly described and the link member ll, which connects each of these end bea'd members I! to the adjacent bead member II, is disposed in each notch II for free pivotal movement.

for the link member punches zztoward one another, without interierence with the substantially spherical bead member ll disposed ture Ila.

After the parts are located as shown in Fig. 5, power is applied to the opposed setting punches 22 and they are thrust together substantially to I x the position shown in Fig. 6, whereby the D01- tidns of the pull tab If surrounding the aperture Il a are upset or compressed together to decrease the size of the'aperture Ila to its final form ll, wherein the compressed or upset portion l2a closely engages the exterior surface of the end bead member I! for attaching it rigidly to the pull tab I2.

The end bead member ll of the bead chain It is thus rigidly attached to the pull tab it and, 1

due to the freedom provided by the notch II ll extending therefrom, the

therebetween in the aperflexibility of the bead chain.

It will likewise appear that I have provided a method for accomplishing the above-described structure with the utmost ease, convenience, rspeed and economy.

It is, 01' course, to be understood that the above description is merely illustrative and in nowise limiting and that I desire to comprehend within my invention all modifications included i within the scope of the appended claim,

ataxia-n1 Patent is:

Having thus fully described my inventiomwhat I clalmasnew and desiretosecurebvlletters A method oi attaching a bead chain to a flat metal pull member for slide iasteners, which comprises providing said flat metal member with an aperture theretbrouzh adjacent one end thereoi! of a size to receive loosely the terminal bead oi the bead chain and a slot extending from said aperture to the adjacent free end 0! said pull member, placing a terminal bead of said bead chain-in said aperture in a central location with --respect to the flat sides of said pull member while the connected portions of said bead chain extend freely through said slot, and compressing the metal around the border of said aperture to move an annular band portion oi such metal laterally into firm spherical gripping contact with the sur-- faces of said terminal bead and thereby decreasing the size oi the aperture through .said pull member and providing a socket in the pull member for the bead.
